SASH-CORD GUIDE.

SPECIFICATION forming part of Letters Patent No. 374,158, dated November29, 1887.

Application filed April 15, 1887. Serial No. 234,893. (No model.)

T at whom it may concern:

' Be it known that I, FRANCIS V. PHILLIPS, of Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Sash-Cord Guides; and I do hereby declare that thefollowingis a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon,

which form a part of this specification;

This invention relates to certain features of construction in the shellsof sash-pulleys or sash-cord guides, which have reference to the mannerof securing the shells in straight [5 through mortises in theframe-stiles.

Primarily the invention consists in the provision of a flange for ascrew or other fastening on the upper end of the shell, which flange isof no greater width than the cord-groove in the sash, and which, insteadof being sunk in the stile, rests thereon and fails to interfere withthermovements over it of the sash, because it is embraced oraccommodated in the cord-groove in said sash. This novel feature may beemployed in conjunction with any suitable fastening or holding means forthe lower end of the shell within the broad terms of my claims; but myinvention consists, seeondarily,in a pulleyshell provided with such a 0superficial flange at its upper end and with a concave lower end,(viewed in side elevation or section,) whereby the lower end of theshell is depressed into the lower wall of the mortise at the innersurface of the stile, and thus held from displacement when the upper endis fastened.

In the accompanying drawings, Figure 1 is a face view of my improvedpulley-shell. Fig. 2 is a central vertical section in the central oplane of the pulley. Fig. 3is a transverse section through a: m of Fig.2. Fig. 4 is a transverse section in the same line (00 a: of Fig. 2) ofa shell not having said guardflangcs.

A represents a pulley-shell cast in'a single 5 piece; 13, a groovedwheel mounted thereon,

over which the sash-cord is trained.

C is a window-stile having a mortise, c, in which the shell A issecured.

As a novel means of securing the upper end of the shell to the stile,the shell is provided with a vertically-projecting flange, A, which liesupon the outer surface of the stile C, and which ,has a hole through itfor the admission of a screw, D, by which to fasten the flange A downfirmly upon the face of the stile C. In order that the flange A may thuslie upon or wholly outside the stile, and yet not interfere with theraising of the sash, said flange is made no wider than the cord-groove,whereby it enters the groove as the sash is raised over this part of theshell.

Any suitable fastening device for securing the lower part of thepulley-shell may, 1nani-' i'estly, be employed; but I have herein shownand described an improved construction for this purpose,intended to beusedin connection with a straight mortise in the window-stilemeaning bya straight mortise one having its end walls at right angles with theface of the stile. This improved construction consists in providing theshell with a relatively narrow cross-piece, a, at its lower end, less inwidth than the thickness of the stile and occupying the outer part ofthe mortise, as shown in Fig.

2. In conjunction with this narrow crosspiece the side walls, a, of theshell are extended longitudinally of the shell beyond the cross-piece a,so that they may be forced into the wood at the inner portion of thelower end of the mortise c, as also plainly indicated in said Fig. 2. Inconjunction with this construction I prefer to make the upper end of theshell downwardly and inwardly inclined, as shown at a and as heretoforemade, so that by first placing the lower end of the shell in the mortiseand then forcing in the upper end the shell will be crowded down todepress itself into the wood of the stile C at the projecting points aand a. In this construction of the shell the flange A, by meeting andresting upon the surface of the stile C, definitely limits the inwardmovement of the shell under a blow of the hammer or other pressure, sothat the shell is easily and quickly brought to place in the mortise.The narrow flange A being arranged to rest upon the outer plane surfaceof the stile C, the trouble and expense of cutting a relish, asheretofore universally done when the shell has had flanges, is saved. Itis very desirable to make the mortise cin the stile C somewhat widerthan the shell, in order to avoid splitting of the stile in driving tobe allowed in the mortise, and yet, in case the pulley-shell to itsplace therein. When the shell is provided with side flanges, as part ofwhat is known as a face-plate, this is easily done,as the side flangescover the spaces thus allowed; but it is the purpose here to avoidcutting a relish at any point, and to utilize the plain mortise as it ishere shown. This of course involves the omission of the side flangesfrom the shell; yet it is desired to provide full or excessive lateralbreadth in the mortise, and. at the same time to fill the mortise on theouter face of the stile to present a worknianlike appearance. To attainthese ends I provide the shell with very narrow and thin ribs or 'fins,a on its opposite sides, which give greater breadth to the shell at thevery face of' the stile than farther inward. These fins fill the littlespaces intended the mortise shall be filled by the body of a shell whichis rather Wider than others, they are l easily depressed into the woodwithout either hindering the insertion of theshell or tending to splitthe stile.

I claim as my invention- 1. A shell of a sash-cord guide, provided withan end flange or projection arranged to bearon the outer plane surfaceof the windowstile, of suitable width to enter the cord-groove of thesash to permit the sash to be raised over the sash-cord guide,substantially as described.

2. A sashpulley shell having a cross-piece or end piece at its lowerend, which extends inward from the front face of the stile, but is ofless horizontal depth than the stile, the side walls of the shell at therear of said lower end piece being extended downwardly beyond the endpiece, whereby said side-wall extensions may be forced into the wood atthe lower end of the mortise in the stile, substantially as described.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
